New Sensors Could Greatly Improve Building Energy Efficiency

Written by , on July 15, 2013

Researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory say that a single advanced building control, now in development, could slash 18% – and tens of thousands of dollars – off the overall annual energy bill of the average large office building, with no loss of comfort. The conclusion is based on extensive […]  Read more »

Solar Panel Balcony Railings

Written by , on September 27, 2012

Sharp has announced that it is launching semi-transparent solar panels designed for balcony railings in apartment blocks. The semi-transparent black solar panels are 1.4 metres wide by 1 metre tall and just 7.6 millimetres thick. They have an efficiency of about 6.8% with a maximum output of 95 watts. While this conversion rate is relatively […]  Read more »

Building Cladding Controls Heat & Purifies Water

Written by , on June 22, 2012

The Center for Architecture, Science and Ecology in New York has come up with a building exterior that not only helps the interior comfortable but purifies water. The exterior surface of the building is clad in modular glass blocks which are configured to capture, refocus and intensify sunlight. Greywater from sinks, showers and hand washing […]  Read more »

White Roofs Shown to Reduce Temperatures

Written by , on March 10, 2012

A study lead by Columbia University scientist, Stuart Gaffin, with the assistance of NASA, has found that white roof coating reduced peak rooftop temperatures New York in summer by an average of 23.6 C°. The study looked at how different white roofing materials performed “in the field” over multiple years. The study tested three different […]  Read more »

Sand Bricks Stronger Than Concrete & Sequester Carbon

Written by , on August 18, 2011

The Japanese company, TIS & Partners, has developed a construction material called CO2 Structure, which is claims hardens quickly, delivers 2.5 times the tensile strength of concrete, is made from cheap materials and sequesters carbon dioxide. High silicon content sand is put into an air tight mould that can be virtually any shape. CO2 is […]  Read more »

Stylish Building-Integrated Solar

Written by , on February 8, 2010

One of the biggest challenges for architects and developers wanting to integrate solar power generation with building materials is aesthetics. Many building-integrated solar technologies are also somewhat inefficient, which means that large parts of a building have to be covered with solar energy-gathering materials to get significant benefits. The Center for Architecture and Science, which […]  Read more »

Green Theatre Initiative

Written by , on October 12, 2008

The Mayor of Lomdon has launched a "Green Theatre Initiative", saying that that “the power of the theatre industry to set an example in the fight against climate change is immense”. The Plan highlights a number of benefits to going green, firstly by allowing theatres to lead the way by “showing our audiences and other theatre […]  Read more »

Green Cement

Written by , on September 4, 2008

Conventional Portland cement is mostly composed of calcium silicates. Its production requires heating limestone and other ingredients to 1,450 degrees C, usually by burning fossil fuels. Making one ton of cement results in the emission of roughly one ton of CO2 – and in some cases much more. Stanford Professor, Brent Constantz, has invented a […]  Read more »

Hybrid Solar/Electric Building at Beijing Olympics

Written by , on July 25, 2008

The Beijing Olympic Village is now home to one of the world’s first photovoltaic/thermal hybrid building systems. Mounted on the roof of one of the central buildings, which will be a service centre for athletes during the Olympics, the system produces both electricity and heat energy from the same surface area, generating 200-300 per cent […]  Read more »

Stick-on Solar Panels

Written by , on May 18, 2008

American roofing company, Lumeta, has developed a stick-on solar panel technology which it says halves the labour needed for installations compared with conventional rack-mounted panels. The panels peak power generation is 380 watts in a typical installation.  Read more »
